Characteristic Analysis of Philip Model and Modified Green-Ampt Model Push Each Parameters
Abstract:The analyses of one-dimensional soil water infiltration in 3 soils were studied through laboratory testing methods used by Philip and Green-Ampt infiltration model.The moisture content of Green-Ampt infiltration model was adjusted to improve the distribution of two model parameters.According to the push each formula,the cumulative infiltration was calculated respectively and was compared with the measured values.The results showed that the modified model can well reflect the soil infiltration properties.The absorption rate(S) of Philip model parameters and Green-Ampt model parameters(kssf) were gradually reduced with the soil viscosity increased.The accuracy of Green-Ampt model parameters(k′ss′f) were high by Philip model modified and showed different degrees of positive effect.It is confirmed that this push each formula could be used to different levels of soil infiltration studied.
